The Three Ellas Run represented a hyperspace route that existed within the Tapani sector. Specifically, this pathway linked the planets of Sorella, Dorella, and Pernella, all of which functioned as ore extraction hubs situated in the Freeworlds Territory. A short hyperlane connected Sorella to the Procopian Shipping Lane via the planet Tanya, a point along that lane. Furthermore, a separate, smaller hyperlane extended from Dorella to the planet Doris. Mirroring other hyperlanes found in the Tapani sector, navigating this route proved challenging due to the presence of space junk.
The first appearance of the Three Ellas Run occurred in Lords of the Expanse, a supplementary work created by Paul Sudlow alongside Chris Doyle and published by West End Games in 1997 for the Star Wars: The Roleplaying Game. It was also referenced in the Player's Guide to Tapani, which was released concurrently by West End Games and authored by Sudlow, in collaboration with Eric S. Trautmann.
